Rumen is a persistent and specific ecosystem consists of bacteria, protozoa and fungus where feed fermentation takes place in it. Produced Hydrogen in rumen can be used in the synthesis of the volatile fatty acids and the microbial protein and its excess would be eliminated through the production of Methane by methanogenesis. Nutritionists have tried to find ways to decrease loss and energy and...

Ziziphora clinopodioides is from the genus of Ziziphora and family of Lamiaceae,which grows in Iran and Turkey. This study was conducted to preserve the chemical and microbial quality of trout fish burger during storage using Ziziphora clinopodioides essential oil (ZEO) individually and in combination with nisin.  Firstly, the chemical composition of ZEO was deter...

Maintaining optimum quality and eliminating dates of contamination, cleanup and packaging to extend the shelf life is one of the country's priorities and policies. Edible coatings with vegetable oils are one way to prevent the growth of microorganisms. In this study, the influence of the coating with natural zein and chitosan polymers along with the essential oil of Roman anise on the microbial...

purpose: to investigate the penetration of cefixime, cephalexin and ciprofloxacin into the human eye based on microbial inhibition by human aqueous samples after oral administration. method: sixty patients aged 40 to 75 years who were scheduled for cataract surgery were divided into three equal groups. one group received 500 mg oral ciprofloxacin 24, 12 and 2 hours preoperatively; another group...

Background: Edible films and coatings have potential benefits for food packaging, particularly meat products. These coatings prevent weight loss and texture changes during shelf life by reducing moisture loss in fresh and frozen meat products. In this study, effect of calcium alginate edible coating on microbial and chemical properties of refrigerated lamb meat over a period of  5 days was...

cumin (cuminum cyminum l.) is one of the most important cultivable medicinal plants in iran and today, it is the second most popular spice in the world after black pepper. it is essential to know the relationships between yield and its components in cumin breeding programs. therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine the relatio...

Due to the increase of microbial resistance to antibiotics and the occurrence of side effects, use of medicinal plants with anti-microbial properties seems to be rational. Hence, in this study, some plants of the Apiaceae, Asteraceae, Brassicaceae, and Cucurbitaceae families were evaluated for antimicrobial effects. The aerial parts of the plants were extracted by different solvents using a Sox...

The expansion of a microbial bank for the degradation of polycyclic aromatic hydrocarbons (PAHs) is crucial for removal of these persistent pollutants. In this study, five gram-negative, aerobic, non-fermentative bacterial strains (III-R3, IV-P11, IV-P13, IV-R13, and V-P18) were isolated from the activated sludge of a petrochemical wastewater treatment plant using enrichment pro­ tocol based on...
